摘要

Restoration of contaminated soil and groundwater could be divided into two phases. The first phase takes aim at reducing human being’s health risks by active remediation,while the second phase aims at eliminating ecological risks by natural attenuation( NA). Because of cost-effective and sustainable cleanup,monitored natural attenuation( MNA) and enhanced natural attenuation( ENA) have been gaining more attention recently,especially in the respects of ecological risk-oriented contaminated land management and a follow-up measure after active remediation. The uses and procedures of MNA for contaminated site cleanup and remediation in USA and EU were introduced firstly,and then possible applications of MNA in China were suggested. More developments and practices of MNA and ENA for managing contaminated sites in China are expected.
